Answers for buyers
Wireless manual call point questions
Does WANLIN-222 detect smoke or heat by itself?
No. The supplied documents present WANLIN-222 as a manual alarm call point. A person initiates the event by operating the button.
What is a wireless standalone manual call point?
It is a manually operated alarm initiation device that sends a fire-alarm event through its documented wireless path. It does not automatically detect smoke, heat or gas.
Can one WANLIN-222 claim cover every radio configuration?
No. The model family alone does not prove identical radio modules, frequency bands, firmware, labels or market evidence across all variants.
Which wireless versions are documented?
A separate manual documents the 433 MHz configuration. Commissioned reports record 4G, LoRa and NB-IoT network modes, while China regulatory records identify a TD-LTE/LTE FDD configuration. Exact hardware and evidence require SKU/BOM confirmation.
What evidence should be reviewed before purchase?
Review the current controlled manual, exact SKU or BOM, radio documents, power details, compatibility record and destination-market requirements. Request model-matched evidence rather than relying on a family name.
